GAS HEATER.

' Application filed February 1o, 1923. serial no. 618,353.

vide a portable gas heater of novel and at- I tractive form, so constructed that it can'be set upon a table or shelf off the floor. Gas heaters as heretofore constructed are primarily designed to stand on the floor and it not infrequently happens that persons walking on the floor will trip against the hose and thereby disconnect it from the burner. Not only are floor burners open to this objection but to the further objection that children like to tamper with them. Inasmuch as my invention is primarilydesigned to be supported on a table or shelf off the floor, the same is less likely to be tampered with by children and there is -no danger of tripping` over the same.

The invention also contemplates the. provision of a gas heater *sov constructed that even if the same should be toppled over no particular damage would be done tothe heater and the fire hazard is reduced to a minimum. f 1

Another object of the invention is to pro vide a gas heater which may be swung in a horizontal plane so as to direct the-heat to any desired point. It is a further object of the invention to provide a gas heater in which the bodyl part thereof is made in sections so as to permit the heater to be packed' in a small compass for storage or shipping and also vto facilitate inspection of the burners. y Y

The above and other novel features will appear from the detailed description taken Y ferred to.

Fig. 7 is a fragmentary view showing the front section as open and Fig. 8 is a modified formof the` invention showing a different form of refractory lining.

lIn the drawings, numeral 10 indicates weighted support having a passageway therein through which gas may floweby way of the stopcock 11 and vertical tube 12.

Telescoped over the tube 12 is a tube 13 having a seat for receiving a gasketrg against which the upper end of the tube 12 may seat to form a gas-tight connection. between the two tubes 12 and 13. The tube 13 extends from a T 14 which is plugged at one end as at 15 and at its other end is connected with a `tube or pipe 16 which extends upward and is connected to the air chamber 17 -of Va burner 18. The burner is preferably provided wlith a circular series of holes 19 through which the gas passes.

The upper part of the T 14 Yconstitutes a saddle 14 for supporting the main body of the heater. The outer casing of the heater is generally indicated by the letter B, and' is held to the saddle 14 byk a clamp block 14a. Mounted on the clampv block is a spring clip 32, which will be subsequently *further resaddle and clamp'blockserve tok clamp the lower section b of the casing B therebetween Bolts 14bv passing through'the and also to .hold the clip 32 in place. This body' or casing is preferably dividedA into hinged sections the numeral 2O indicating one hinge and numeral 21a second hinge, 'these hinges beingaHiXed to a lower section b of the casing. Reference characters 2Oil and 21b indicate the sidesections of the casing. The free ends of these sections are provided with aligned openings for receiving a removable locking pin 22 as will be'read'ily understood frominspection of the various One endof thel casing B is also provided with a hinged member 23 the hinge thereof being indicated at 24 which is also afixed to the section b. This hinged end has agycircular opening and is adapted to be held in normal position by means of the two hinged sections 2()a and 20h, the same being provided with an inturned ilange 25 behind which a circumferential edge of the end Q3 is adapted to be received.

The other end of the casing B is closed by a plate or wall 26 which is preferably secured to the bottom section b of the body or casing by means of a removable pin Q7. The hinged sections "L and 2lb are provided with inturned flanges 2S behind which the peripheral edge of the wall or plate 2G may be received. The flanges and Q8 at either end of the sections 2Oa and 20h provide a neat and solid joint with the members QS and 2G.

The end wall 26 is provided with an opening through which the reduced neck 1T ot the air chamber 1T enters. the burner 1S beingl suitably attached to the cud o'll the neck and being disposed adjacent to the wall 26, it being spaced therefrom by suitable insulating material S such as abestos.

Arranged and supported within the casing or body is a refractory shell R which at one end has an opening corresponding to the opening at the end Q3 of the casing B and at the other end has an opening which is adapted to receive the burner 18. The opening in the shell R into which the burner enters is sutliciently large to leave an annular space between the burner and shell. and this annular space is in connection with the atmosphere by means oit aJ plurality of passages B0 through which air will enter. It will be noted that the passages terminate behind the row ot holes 1l) in t-he burner and consequently there is no danger ot the llames passing out through said passages. Further-- more by reason of this arrangement air will be drawn into the shell through these passages and the tendency will be for the heated air to leave by the open end ot the refractory shell.

In order .to permit easy lighting of the gas burner there is provided Aa conduit 531. which extends through the shell li. and side ol the hinged body section and through this conduit a. y lmatch or the like Vmay be inserted to light the gas. rl`his opening also supplements the passages 30 through which air may enter the interior oi" the shell.

The refractory shell R is preferably supported in the spring-clip 32 which is secured to the saddle 1l. There is preferably provideda suitable insulating material betweenv the refractory shell or lining R and the casingl B, this insulating material being generally identilied as S throughout the several views. The refractory lining or shell is preferably' a` baked clay prochict7 so that after saine hasV once become heated it will maintain its hea-ted condition tor a considerable Jeriod of time vand will. allow a less quantity of gas tobe used to keep the said lining or shell in a heated condition.

lVhile I prefer that the refractory shell or lining R shall be a clay product it is within the spirit of the invent-ion to make the same ot' other material such as a metal shell lined on its interior with asbestos or other fire resisting mate-rial. Fig. S shows this form of the invention and indicates the metal shell and 36 the interior lining thereof` Instead of providing an annular space between the burner and adjacent end of the. metal shell, the shell may snugly telescope the latter. The equivalent of the annular space may be Obtained by causing the shell to flare upwardly behind the openings 19 in the burner and this upward tlare may be connected with passages 30* leading to the atmosphere.

lllhen it is desired to disassemble the invention for sto-ring or shipment it is merely necessary to remove they various pins which hold the sections of the. casing in place and the other parts can then be removed and readily packed. The base part of the heater is readily separable from the upper part thereof by reason of the telescopic connection 12 and 13.

The specification sets forth the main fea.- tures ot the invention but it will be readily apparent to those skilled in the art that t-he details of the structure may be widely varied without departing from the substance or real essence of the invention.

Vhat- I claim is:

1. In a gas heater, the combination of a burner, a cylindrical casing into one end ot which the burner enters, said casing being divided into sections, one of said sect-ions being swingable on a pivot extending transversely to the axis of said body and the other sections being swingable on axes parallel to the axis of .sa-id casing.

2. In a gas heater, the combination with a support, of a horizontally disposed cylindrical casing turnably mounted :for movement in a horizontal plane, and a. gaseouduit leading from one end ol the casing lo the said support. i

3. In a gas heater, the combination with a cylindrical casing, ot' an external radial tube axed thereto and turnably mounted on a iio support, a pipe in connection with said tube and terminating adjacent one end of the casing, and a burner within the casing and in connection with one end. of the pipe.

4. In a gas heater, the combination of a saddle having a spring-clip. a cylindrical Shell seated in said spring-clip, a burner at one end of said shell and the other end ot the shell being open, a casing for said shell including a pair of segmental sections hinged to either side of the saddle and means for holding said sections in closed position about the said shell.

5. In a gas heater, the combination of a saddle, a horizontally disposed cylindrical shell seated thereby, a tube axed to the saddle and extending radially with respect to said shell, a pipe in connection with said tube leading toward one end of the shell, and a burner within the shell and in connection with the pipe. Y

6. In a gas heater, a saddle having a downwardly projecting tube, a pipe in connection with the tube and extending horizontally therefrom for a distance and then bent upwardly,-a horizontally disposedgas burner at one end of the pipe, a cylindrical the heat from the burner may be projected, a casing within which the said-shell is enclosed, and means on the saddle for sup-v porting the said casing.- y

7. The combination as specified in claim 6, said casing consisting of a plurality of members hinged at their lower ends so as tok open` outwardly when desired.

In testimony whereof I ailix my signature.
